Objective

. Relate the information serch tendencies about Emtricitabine/Tenofovir and Pre-exposure prophylaxis for the human immunodeficiency virus (HIV) in Spain.

Methods

. Ecological study of the relative search volumen obtained from direct consultation to the tool «Google Trends», using the search topics «Emtricitabine/Tenofovir» and «Pre-exposure prophylaxis for HIV», and «Truvada» as search term. The search periodo from January 1, 2004 to December 31, 2019. Inquiry date January 23, 2020.

Results

. The VBR = 100, máximum, it was achieved in October 2019 for «Pre-exposure prophylaxis for HIV», being the relationship between the terms of 100/17/15. The association between «Emtricitabine/Tenofovir» and «Truvada» was very high (R = 0,99; p < 0,001). And the mean of the VBR for «Emtricitabine/Tenofovir» and «Pre-exposure prophylaxis for HIV» were 12.20 and 27.20 respectively. The VBR tendencies for «Emtricitabine / Tenofovir» was slightly increasing with linear adjustment (R2 = 0.05; p <0.02), for «Pre-exposure prophylaxis for HIV» it was moderately increasing with exponential adjustment (R2 = 0.20; p <0.001). The correlation between the VBR data of the two topics analyzed didn't show an association between them (R = 0.04; p = 0.595).

Conclusions

. Growth was found over time in the search of information on both the Emtricitabine/Tenofovir and HIV Pre-Exposure Prophylaxis Topics, although the existence of an association between both Topics could not be proved. The increased search for this information could be related to the increased interest in the prevention of risk sexual practices related to HIV.
